BASIC STEAM PISTON ENGINE FOR NAVAL USE
First time making a steam engine! Absolutely no idea if it’s good, but hey... The piston shaft does a solid 1.5 rps... Before the gearboxes politely disagree. For power generation, just slap a turbine on the steam exhaust before the condensers.
! This design has been extensively untested and is guaranteed to possibly do something. !
PS: Expensive, big, and impractical... But at least it's golden!
